Covalently Bonded PIDA on SBA-15 as Robust Pd Support: Water-Tolerant Designed Catalysts for Aqueous Suzuki Couplings

摘要

In this work, a new catalyst based on Pd (II) supported SBA-15 has been has been introduced and discussed. The designed catalyst was characterised by Scanning electron microscopy (SEM), transmission electron microscopy (TEM), FT-IR, BET surface area analysis, thermo gravimetric analysis (TGA), Energy-dispersive X-ray spectroscopy (EDS) and atomic absorption spectroscopy (AAS) analyses. For the first time, lobster-like N-propyliminodiacetate (PIDA) has been incorporated as ligand onto SBA-15 to form a stable complex with Pd ions to design a highly active, stable and reusable catalyst for Suzuki-Miyaura couplings.
